PRESSURE DEVICE.

SPECIFICATION forming part of Letters Patent No. 284,044, dated August28, 1883. Application filed May 19,1883. (No model.)

To. all whom it may concern:

Beit known that I, WILLIAM A. Moonn, a citizen of the United States, anda resident at Sherman, in the county of Grayson and State of Texas, haveinvented certain new and useful Improvements in Pressure Devices 5 and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, andshows a front view of the device inside of a half-barrel, shown insection. Fig. 2 is a perspective view. Figs. 3, 4, 5, 6, and 7 aredetail views of the different parts.

This invention has relation to portable pressure devices for use incasks, boxes, barrels, or other receptacles; and the invention consistsin the construction and novel arrangement of the pointed dogs andcam-levers pivoted together, and in the combination therewith of apivot-bolt having its nut secured by means of a locking-key, all ashereinafter set forth.

In the accompanying drawings, the letters a and b designate two dogs,having pointed outer ends, '0, and being connected together by apivot-bolt, c, at their lower ends. This pivot-bolt also connects thecam-levers d and e, the bolt passing through said levers near ter isturned on the bolt. grooved transversely in its face, as indicated at m,in order that the wire or key may be drawn into the groove, and therebylock the nut on the bolt.

The pressure device is operated by adjusting the pointed ends 11 of thedogs outward, so that they will engage the side walls of the box orbarrel or other receptacle containing the material to be put underpressure. The camlevers, which are pivoted to the dogs, areat firstarranged in horizontal or nearly horizontal position. In order to applythe pressure on the follower f, the handles of the cam-levers are raisedand brought toward each other, so that through the purchase obtained bythe dogs the cam-edges g of the levers are brought to bear, forcing thefollower downward.

This pressure device is designed to servevarious useful purposes inconnection with barrels, boxes, and other common receptacles, as itenables articles placed therein to be packed in small space or held downunder brine or other liquid.

Having described this invention, what I claim, and desire to secure byLetters Patent,

1. Apressure device consisting of the pointed dogs a b and thecam-levers d and e, pivoted together, and adapted to be used inside ofabarrel or other receptacle, substantially as specified.

2. The combination, with the pointed dogs a b and the cam-levers d e, ofthe grooved bolt 0, grooved nut 70, and the key or lookingwire h,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
